[0002] In the field of mechanical manufacturing and processing, tapping is a common process operation. Traditional tapping machines usually adopt the method of connecting a single tapping chuck to a driving motor to tap the processing holes of workpieces one by one. This method is inefficient. For the processing requirement of parallel multi-hole tapping on the same end of a workpiece, multiple operations are required, increasing the processing time and cost. Therefore, there is an urgent need for a chuck tapping machine that can achieve synchronous multi-hole tapping and is easy to operate.

[0015] The technical solution of the utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Embodiment 1

[0017] As Figure 1 , Figure 2 and Figure 3 shown, a new chuck structure of a tapping machine proposed by the utility model includes a base 9, a bracket 2 is slidably connected to the front end of the base 9, a top plate is provided at the top of the bracket 2, a first motor 1 is installed on the top surface of the top plate, a driving shaft 3 is arranged inside the bracket 2, the output shaft of the first motor 1 passes through the top plate and is connected to the driving shaft 3 through a coupling, a driving gear 4 is fixedly connected to the end of the driving shaft 3, a bottom plate is provided at the bottom of the bracket 2, tapping chucks 5 are installed at both sides of the bottom end of the bottom plate, transmission shafts of the tapping chucks 5 at both sides pass through the end face of the bottom plate and driven gears 8 are arranged on one side of the top end of the bottom plate, the driven gears 8 at both sides are meshed and connected with the driving gear 4, and a bit 6 is detachably clamped at the bottom of the tapping chuck 5.

[0018] In the embodiment, a slide rail is arranged vertically at the front end of the base 9, a slider is slidably connected to the slide rail, and the other end face of the slider is fixedly connected to the back end face of the bracket 2 for guiding.

[0019] In an embodiment, a lead screw 901 is provided vertically at one end of the back of the base 9. The top end of the lead screw 901 is connected to a second motor 10 through a coupling. The second motor 10 is fixedly installed above the top of the base 9. The lead screw 901 is slidably connected to a slide table 902. The front end of the slide table 902 passes through the front substrate of the base 9 and is drivingly connected to the back end face of the bracket 2.

[0020] In an embodiment, a plurality of support columns are provided between the top plate and the bottom plate of the bracket 2. The periphery of the bracket 2 is connected with side plates that enclose the bracket 2, which plays a role in dust prevention.

[0021] In an embodiment, one end of the bottom of the bottom plate close to the base 9 is connected with a baffle 7. The baffle 7 extends downward, and its end face blocks between the rear end of the tapping chuck 5 and the front end of the base 9, so as to prevent the generated debris from splashing and colliding with the tapping machine device during tapping, resulting in the debris entering the gap of the tapping machine and reducing the service life of the tapping machine.

[0022] The working principle of a new chuck structure of a tapping machine based on Embodiment 1 is as follows: When the present utility model is used, the output end of the first motor 1 passes through the top plate of the bracket 2 and is connected to the drive shaft 3. A driving gear 4 is installed at the bottom of the drive shaft 3. The driving gear 4 rotates and meshes with the driven gears 8 at both ends. The rotation of the driven gears 8 drives the transmission shaft fixedly connected to the driven gears 8 to rotate. The transmission shaft transmits power, so that the tapping chuck 5 drives the bit 6 to rotate; the rotation of the second motor 10 drives the lead screw 901 to rotate, so that the slide table 902 connected to the lead screw 901 moves along the thread spiral direction on the surface of the lead screw 901. Thus, the bracket 2 is driven by the slide table 902 to slide vertically along the front end slide rail of the base 9, for driving the bracket 2 to drive the two tapping chucks 5 to perform lifting movements; when lowering, the bit 6 at the front end of the tapping chuck 5 gradually approaches the end face of the workpiece, and the bit 6 rotates to tap the end face of the workpiece; after tapping is completed, the second motor 10 drives the bracket 2 to drive the tapping chuck 5 to lift away from the workpiece, and then the next workpiece can be replaced for tapping operation.

[0023] The above specific embodiments are merely several preferred embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
